Germinating Marijuana Seeds

Germinating marijuana seeds is comprised of supplying the seed with moisture and keeping it in a dark place that has a fairly constant warm temperature. When you're ready to wake up your seeds you're going to ponder how to germinate your marijuana seeds. Marijuana seeds germination depends on many factors, both internal and external. The most important external factors include: water, oxygen, temperature, light and proper grow medium. Some cannabis seeds, like pure Sativas require up to 5 C degrees / 10 F degrees higher temperature because they come from much hotter climate. It is a good idea to place some type of B1 additive in the water used to germinate the seeds. There are a number of types of this vitamin supplement sold commercially. There is Ortho Up-Start, Super Thrive, Hormex, Power-thrive and a number of other additives which have this vitamin supplement.

Internally, water is essential here, for as soon as the seed has absorbed a sufficient amount of water, the seedling begins to form its root system. Once the seed coat is cracked, which can take 2 to 10 days, the germinating seedling requires lots of oxygen for its metabolism. Oxygen is vital for successful germination. If the soil is waterlogged, it might cut off the necessary oxygen supply and prevent the seed from germinating as it prevents respiration, which is the main source for the seedling's energy until it starts to photosynthesize. At this time light and soil have to be provided to maintain healthy germination process. When the appropriate conditions are given to the seed for a long enough time, the plant will sprout a root. After the root is about a quarter of an inch long, the seed can be placed in an environment where it can grow. Regardless of the cannabis growing method, the first thing you will need to do is learn how to germinate marijuana seeds. There are a few standard ways this is done.

Germinating Marijuana Seeds In The Grow Medium

Place the seeds under the surface in the growing medium at approximately the size of the seed. Position the marijuana seeds in soil with pointed end up. Regularly sprinkle the growth medium with water, but make sure that the grow medium does not become too wet. The seedling uses the spare food present in the seed for growing. Air is very important for its metabolism. So make sure that the soil remains sufficiently airy. One of the characteristics of Rockwool is that it retains much air. Make sure that the rockwool is not standing in water and that the excess water is able to drain away properly. Rockwool has a fine germination climate for the seeds. Remove the cover as soon as the seedlings reach above the medium.

It is not suggested germinating seeds directly in outdoor soil, even if the final destination of the plants will be outside. Your precious seeds will have a higher survival rate and be healthier if germinated indoors. You can germinate the seed directly on the spot where it will grow. Simply place the seed where you want the plant to grow and cover it with about a half inch of loose soil.

There are many different soil mixtures which facilitate seed germination. One of the best starts with potting soil and coarse horticultural perlite. To this mix add two heaping tablespoons of horticultural hydrated lime. The lime helps to balance the pH and will add secondary nutrients like calcium and magnesium. Also add a half gallon of some other nitrogen-bearing organic, such as pasteurized cow manure, pasteurized worm castings, or pasteurized bat guano. The organic ingredients will supply nutrients and their fiber will help texture the man-made soil. he materials are mixed together thoroughly. A mask should be worn whenever these ingredients are mixed. If they are mixed indoors, a fan blowing over the work area and out a window or door will be helpful. If the materials are moistened with the distilled water before mixing they will produce less dust as you work.

The pH of any medium should be kept between pH 6 (slightly alkaline) and pH 8 (slightly acid), or as close to the marijuana's ideal pH of 7. This is a neutral pH? A hand held pH meter will give an accurate reading of most mediums you will use. Commercial soils are usually never alkaline, if anything they are closer to neutral or acid. This means that you may sometimes find that your pH is slightly higher than it should be. If this is the case, put a tablespoon of horticultural hydrated lime into a gallon of water, and pour it over the medium. Check the pH of your medium every few days.

Seeds germinated in soil should be germinated in smaller two to three inch containers. The most common of these are the peat moss trays or plastic cups. The soil mixture is placed in the cup tray almost to the top and the mixture is lightly pressed. The medium should be watered until water just starts to drip out the bottom of the container. If peat moss cups are used, the peat cup should be moistened with tepid water. The container of medium is then lightly watered with a solution of a vitamin B1 supplement.

Grow trays will help grow medium containers retain heat. A nice technique is using heating pads. These trays are also sold with plastic see-through tops, which will create a greenhouse atmosphere and raise the humidity. Evaporation of moisture will lower the temperature of the sides of the trays. For this reason either a heating pad or some other assurance of temperature control should be used. The seedlings require an 80-90?F (27-32?C) ambient temperature.

Germinating Marijuana Seeds In Paper Towel

If you plan on growing marijuana hydroponically, you can germinate the seed on paper towel or directly on a small piece of the media that will be used in your hydroponic garden. You can start seeds in this method that will be grown in soil or hydroponically. Substitute your media for the paper towels. Take your hands, a plate, a bowl and be diligent to obtain a clean anti-bacterial environment to germinate marijuana seeds. Slightly wet down a paper towel, then squeeze the paper towel leaving it damp. Fold your paper towel to fit on the bottom of the plate. Turn the bowl upside down and place it over the plate making sure the paper towel does not slip outside the edge of the bowl. Check to make sure the temperature of the paper towel is warm as cold will not work. Place the seeds on top of the damp paper towel then cover them with the bowl again (some people also like to put another damp layer of paper towel over the top of the seeds and omit the bowl). The plate and bowl should be dark enough to block sunlight or kept in a dark area or covered to block sunlight and stored in an area that is clean and warm.

Check daily and add small quantities of water when needed to keep the paper towel moist. Tap water probably contains chlorine and other elements that are not seed friendly. If you only have access to tap water, allow it to age uncovered for at least three days. Better still, use distilled or reverse osmosis water. When the seeds sprout, and the white shoot emerges about a quarter inch, transplant (root down) into your hydroponic garden or soil. Treat very gently, don't touch or break the root tip.

Germinating Marijuana Seeds In Rockwool or Hydroponically

Some growers will want to germinate their seeds in rockwool cubes, coconut fiber cubes, lava rock or Oasis felt-type cubes. These items are all porous materials, which have the ability to hold water for a long period of time. Rockwool is a heated and spun material. Rockwool cubes should be pH balanced before use. Coconut fiber will biodegrade faster than rockwool. The Oasis cubes are made of a pH neutral, porous felt-type material, one of the world's favourite mediums for germination. They may be purchased as 12 inch x 24 inch slabs, which fit perfectly into similar sized rooting flats or trays. Regardless of whichever of these mediums is used for germination, the process is the same. First place the medium in the flats and moisten them to saturation point. They are watered in the flats and a hole is punched in the center top of each cube. A seed is placed point end down. The cubes are watered a second time utilizing the vitamin B1 root stimulant. Any standing water is drained off. Plastic covers may or may not be needed to maintain additional humidity. The flats (trays) are placed on heating mats, and placed in a dark place. Water as required, the cubes are kept moist, there should be no standing water in the trays, always pour off any excess water after watering. You should have root sprouts in 2 to 10 days.

Germinating Marijuana Seeds in Water

Germinate marijuana seeds in clean water. Most municipal water supplies have clean, pH neutral water that is very suitable for germination. A small amount of chlorination is beneficial for killing a lot of the parasites in the water. If the local water supply is not of good enough quality to drink then don't use it to germinate seeds. Bottled spring water, without additives or carbonation, is usually a good source of water for germination. For best germination results, fill a glass with clean, room temperature water. Drop marijuana seeds into the water. The seeds should be left to soak in a dark warm place (65 - 80 degrees F). A kitchen cupboard is usually suitable. Check the seeds about every 12 hours. Tap down the seeds that are floating with your fingertips, don't worry if they continue to float. Usually within 48 hours the seeds swell and split their outer seed casings. DO NOT continue soaking after the white, initial roots are visible at the crack in the seed casings. The seeds are ready to plant at this point. Soaking the seeds until the roots are exposed can result in stressful, early root damage.

Germinating Marijuana Seeds In A Sprouting Box Greenhouse

The best al around sprouting method is probably to make a sprouting box (as sold in nurseries) with a slated bottom. The sprouting soil should be a mixture of humus, soil, and sand. Add organic fertilizer and water mixed in about one week before planting. Soil growers who plan on growing marijuana either indoors or outdoors can use a mini-greenhouse with a heating element. These are used to germinate the seed and let it start to grow and establish a root system in soil, without being transplanted. Seeds are germinated by placing soil in the tray of the mini-greenhouse and moistening it with water. The seed is then placed about half an inch under the soil, and the top is placed on the greenhouse. The greenhouse is moved to a dark area and the heater is plugged in. After the seed has germinated, the heat is stopped and the plants are supplied with about 16 hours of mild light per day (fluorescent, led, or diffused sunlight only, not metal halide, high pressure sodium, direct sunlight, or any source of strong light) and allowed to grow a bit before being transplanted into the soil that they will be grown in. When ready to transplant, you must be sure and leave a ball of soil around the roots of each plant. This whole ball is dropped into a baseball-sized hold in the permanent soil. If you are growing marijuana indoors, you should use a green safe light (purchased at nurseries) during the transplanting operation. If you are transplanting outdoors, you should time it about two hours before sunset to avoid damage to the plant. After the plants are set in the hole, you should water them. It is also a good idea to use a commercial transplant chemical (also purchased at nurseries) to help then overcome the shock.

**Temperature And Marijuana Seed Germination

An average temperature of about 70-75 degrees F will be fine for germinating most seeds strain. But higher temperatures might be necessary to ensure optimal speed and health when germinating seed strains that originated in areas where it is very warm all year long.

If you don't know where your seed strain originated, try germinating a single seed in an area where the average temperature is 70-75 degrees F. If your seed doesn't sprout, try germinating another seed at a temperature 5 degrees F higher until you find what temperature works best.

Of the 20+ marijuana strains the author has grown, only 3 marijuana strains had problems germinating at temperatures between 70-75 degrees.

The strains that wouldn't sprout in an area where the temp was about 70 degrees (average temp) were moved to an area where the temp was about 75 degrees (average temp) and still didn't sprout. So another seed was started in an area where an average temp of 80 degrees was maintained.

It was only when these seeds were germinated at average temperatures of 80 degrees fahrenheit or higher that they sprouted. All the strains that required fairly high temperatures to germinate were equatorial in origin, so they need hot weather conditions (like in nature where they come from).

When germinating marijuana seeds:
Most seeds will germinate at 70-75 degrees F.
Nearly all seeds do best at about 78-80 degrees F.
Some seeds may require temperatures up to 80-85 degrees F.
Never exceed 90 degrees F when germinating marijuana seeds.

When required, a seedling heat mat can be employed to raise and/or maintain a higher temperature when germinating seeds. Most heat mats radiate heat on both sides, so when warmer temps are required, you can put some kind of insulation (rigid styrofoam works well) under the mat and more heat will be radiated upwards.
